Grafana: bargauge ECS service tiles on Overview dashboard#4742
Conversation
Five tiles (Realm Server, Prerender, Prerender Mgr, Worker, Synapse)
each cram three values (CPU / Mem / Tasks or Up) into a w=4 stat
panel — every number ends up tiny next to the single-stat Postgres
tile in the same row.
Switch them to horizontal bargauge with gradient fill so each metric
gets a full-width bar plus a value, scannable at a row level. Postgres
stays a stat (one number, already works).
Per-field max values so the bars fill meaningfully:
- Tasks (CloudWatch RunningTaskCount): max 10
- Synapse Up (`count(up{job="synapse"} == 1)`): max 1
- Synapse Mem (`process_resident_memory_bytes`): max 8 GiB
CPU and Mem percentages keep the implicit 0–100 from the `percent`
unit. Existing thresholds and field display names carry through
unchanged, so green/yellow/red coloring still matches the prior tile.

Summary
Five service tiles on the Overview dashboard's third row (Realm Server, Prerender, Prerender Mgr, Worker, Synapse) cram three values into a w=4 stat panel — numbers are unreadable. Convert them to horizontal bargauge so each metric gets its own full-width bar + value, scannable at a glance.
